Description

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Application
No. 62/370,787 filed on Aug. 4, 2016. The above identified patent
application is herein incorporated by reference in its entirety to
provide continuity of disclosure.

BACKGROUND OF THE INVENTION

[0002] The present invention relates to exercise devices. More
specifically, the present invention relates to an exercise device
including multiple crossbars and a bracket, which conjunctively
facilitate multiple exercises such as push-ups, sit-ups, leg lifts,
step-ups, and the like.

[0003] One of the best forms of exercise to improve muscle tone and
strength, as well as to increase overall fitness, is isometric weight
training, in which the exerciser may use his or her own body weight as
resistance against muscular movement. For example, a number of common
upper-body and abdominal exercises utilize isometric resistance,
including dips and push-ups for upper-body muscular development, and leg
raises or crunches for abdominal muscles.

[0004] Isometric exercise apparatus are generally advantageous in that
they do not necessitate the implementation of moving parts or
supplemental weights for their utility, or a second person to spot the
exerciser. However, isometric exercise apparatus are nevertheless
typically quite heavy and bulky, and are usually not portable. In
addition, these apparatus are commonly incorporated into expensive
multi-station gyms, which occupy a substantial area of floor space.
Accordingly, such exercise devices are often ill suited for home or
office use because of their bulk and their non-portability.

[0005] Furthermore, these exercise machines are limited in their
functionality because they are typically adapted for one type of
exercise, such as push-ups or abdominal crunches. Therefore, there is a
need for an affordable, easy-to-use, lightweight, and portable
stand-alone exercise device which can be positioned underneath a door and
secured thereto in order to perform a range of exercises including, for
example, push-ups, dips, sit-ups, leg raises, and step-ups.

SUMMARY OF THE INVENTION

[0006] In view of the foregoing disadvantages inherent in the known types
of exercise devices now present in the known art, the present invention
provides an exercise device wherein the same can be utilized for
providing convenience for the user when exercising.

[0007] In one example of the present invention, the exercise device
comprises a an upright frame including a first support member and a
second support member, each members including an upper end, a lower end,
and a front and rear leg each including a first end and a second end. A
first crossbar interconnects the upper end of the first support member to
the upper end of the second support member, such that the first crossbar
is perpendicular to the first and second support members. A second
crossbar interconnects the upper end of the first support member to the
upper end of the second support member, such that the second crossbar is
perpendicular to the first and second support members. A third crossbar
interconnects a middle portion of the rear leg of the first support
member and a middle portion of the rear leg of the second support member,
such that the third crossbar is perpendicular to the first and second
support members. A fourth crossbar interconnects the second end of the
front leg of the first support member and the second end of the front leg
of the second support member. A bracket extending outwardly from the
fourth crossbar includes a planar member and lip configured to receive a
door rail. A height adjustment member coupled to a base of the each of
the front legs is configured to extend vertically downwardly from the
base of each of the front legs so as to adjust the height of each of the
front legs. A first support arm and a second support arm extend
horizontally outwardly from the upper end of the first support member and
the second support member, respectively.

[0015] The first and second support members 20, 25 each include an upper
end 70, a lower end 75, a front leg 80, a rear leg 85, and a support bar
90, which are all coplanar relative to each other. In the depicted
embodiment, each of the first and second support members 20, 25 are
formed from a single unitary tubular member. The upper ends 70 of the
support members 20, 25 extend horizontally and interconnect a first end
95 of the front legs 80 to a first end 100 of the rear legs 85. The
support bar 90 extends horizontally across the lower end 75 and
interconnects a second end 105 of the front legs 80 to a second end 110
of the rear legs 85, thereby providing support to the lower end 75 of the
support members 20, 25, when the exercise device 10 is bearing weight.
Each of the rear legs 85 extends vertically along a linear axis, such
that the rear legs 85 are perpendicular relative to the upper end 70 of
the support members 20, 25. In the depicted embodiment, each of the rear
legs 85 includes a stopper 86 disposed at a base 88 thereof for gripping
a surface. The stopper 86 is preferably composed of a high-friction
material, such as, for example, rubber. Each of the front legs 80
includes an arcuate portion 115 extending, or curving, outwardly from the
first end 95 of the front leg 80 to the second end 105 of the front leg
80. The curved portion 115 extends outwardly relative to the upper end
70, such that the first end 95 and the second end 105 of the front leg 80
are offset and disposed along different vertical planes.

[0016] The first crossbar 30 interconnects the upper end 70 of the first
support member 20 to the upper end 70 of the second support member 25
adjacent the front legs 80, such that the first crossbar 30 is
perpendicular to the first and second support members 20, 25. The second
crossbar 35 interconnects the upper end 70 of the first support member 20
and the upper end 70 of the second support member 25 adjacent the rear
legs 85, such that the second crossbar 35 is perpendicular to the first
and second support members 20, 25. The first and second crossbars 30, 35
are aligned and parallel relative to each other along the same horizontal
plane. The first and second crossbars 30, 35 are aligned and parallel to
each other so that they form a level area in which a user can step onto
when performing step-ups using the exercise device 10. In the depicted
embodiment, the first and second crossbars 30, 35 each include a first
pair of grips 120 for providing a user comfort and stability when
utilizing either of the crossbars 30, 35. Each grip of the first pair of
grips 120 extends annularly around its respective first and second
crossbar 30, 35. In another embodiment, the first and second crossbars
30, 35 each include a grip extending along the length of each of the
crossbars 30, 35.

[0017] The third crossbar 40 interconnects a middle portion 125 of the
rear leg 85 of the first support member 20 and a middle portion 130 of
the rear leg 85 of the second support member 25, such that the third
crossbar 40 is perpendicular to the first and second support members 20,
25. In the depicted embodiment, the third crossbar 40 includes a second
pair of grips 135 for providing a user comfort and stability when
utilizing the third crossbar 40. The third crossbar 40 is configured to
receive a user's feet when a user is performing sit-ups or crunches using
the exercise device 10. For instance, in one use of the exercise device
10, a user places his or her heels on the third crossbar 40 and places
his or her toes between the first crossbar and the second crossbar 35 in
order to support the upper portion of his or her toes with the second
crossbar 35, as shown in FIG. 3, such that the user may utilize the
exercise device to perform sit-ups.

[0018] The fourth crossbar 55 interconnects the second end 105 of the
front leg 80 of the first support member 20 and the second end 105 of the
front leg 80 of the second support member 25, such that the fourth
crossbar 55 is perpendicular relative to the first and second support
members 20, 25. In the depicted embodiment, the bracket 60 comprises a
pair of outwardly extending planar members 140 each including an upwardly
extending lip 145 disposed at a distal end thereof. Each of the planar
members 140 is sized to receive the bottom rail, or edge, of a door and
secure it thereto in order to stabilize the exercise device 10 to the
door when performing exercises requiring the exercise bar 10 to be fixed
in place, such as crunches or sit-ups, as shown in FIG. 3. The lip 145
engages the front or rear face of the door rail and prevents the exercise
device 10 from slipping out from under the door when in use.

[0019] The height adjustment member 65 is extendably coupled to a base 150
of each of the front legs 80 of the first and second support members 20,
25. The height adjustment member 65 is configured to extend vertically
downwardly from the base 150 of the front legs 80 so as to extend the
height the front legs 80 and the fourth crossbar 55 relative to the
ground. In this way, the front legs 80 and the fourth crossbar 55 may be
raised in order to engage a door that includes a door rail positioned at
a greater height than an average door, as shown in FIG. 3. In the
depicted embodiment, the height adjustment member 65 is threadably
coupled to the base 150 of each the front legs 80, such that the height
adjustment member 65 can extend and retract into the base 150 of each of
the front legs 80 of the first and second support members 20, 25 via a
twisting motion.

[0020] The first support arm 45 extends horizontally outwardly from the
upper end 70 of the first support member 20 and the second support arm 50
extends horizontally outwardly from the upper end 70 of the second
support arm 50. The first and second support arms 45, 50 are aligned with
one another along a common longitudinal axis. In the depicted embodiment,
